Electromechanical elementary relays - Part 1: General and safety requirements (IEC 61810-1:2015)

This part of IEC 61810 applies to electromechanical elementary relays (non-specified time allor-
nothing relays) for incorporation into low voltage equipment (circuits up to 1 000 V
alternate current or 1 500 V direct current). It defines the basic functional and safety
requirements and safety-related aspects for applications in all areas of electrical engineering
or electronics, such as:
• general industrial equipment,
• electrical facilities,
• electrical machines,
• electrical appliances for household and similar use,
• information technology and business equipment,
• building automation equipment,
• automation equipment,
• electrical installation equipment,
• medical equipment,
• control equipment,
• telecommunications,
• vehicles,
• transportation (e.g. railways).
Compliance with the requirements of this standard is verified by the type tests indicated.
In case the application of a relay determines additional requirements exceeding those
specified in this standard, the relay should be assessed in line with this application in
accordance with the relevant IEC standard(s) (e.g. IEC 60730-1, IEC 60335-1, IEC 60950-1).

Electromechanical elementary relays - Part 1: General and safety requirements (IEC 61810-1:2015)

Relais électromécaniques élémentaires - Partie 1: Exigences générales et de sécurité (IEC 61810-1:2015)

L'IEC 61810-1:2015 s'applique aux relais électromécaniques élémentaires (relais de tout ou rien à temps non spécifié) destinés à être incorporés dans des matériels basse tension (circuits jusqu'à 1 000 V en courant alternatif ou 1 500 V en courant continu). Elle définit les exigences fondamentales fonctionnelles et de sécurité ainsi que les aspects liés à la sécurité, destinés à être appliqués dans tous les domaines de l'électrotechnique ou de l'électronique, tels que: l'équipement industriel général, les installations électriques, les machines électriques, les appareils électriques pour usages domestiques et analogues, les matériels de traitement de l'information et les matériels de bureau, les automatismes du bâtiment, les appareils d'automatisme, les appareils pour installations électriques, les appareils médicaux, le matériel de contrôle, les télécommunications, les véhicules, le transport (par exemple, chemins de fer). La conformité aux exigences de la présente norme est vérifiée par les essais de type indiqués. Au cas où l'application d'un relais détermine des exigences supplémentaires dépassant celles spécifiées dans la présente norme, il convient que le relais soit évalué par rapport à cette application, conformément à la ou aux normes IEC correspondantes. Cette quatrième édition annule et remplace la troisième édition parue en 2008. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - introduction de deux procédures d essai principales: procédure A qui reflète la procédure de l'édition 3 de la présente norme et procédure B qui reflète l'évaluation réalisée conformément aux exigences nord-américaines; - inclusion d'essais pour des appareils dédiés à des applications particulièrement appropriées aux applications sur le marché nord-américain (voir Article D.1); - introduction des essais dans des conditions de montage simple; - clarification des exigences d'isolation après les essais d'endurance; - inclusion de dispositions applicables aux exigences de sécurité de base; - mise à jour des références.

Elektromehanski osnovni releji - 1. del: Splošne in varnostne zahteve (IEC 61810-1:2015)

Ta del standarda IEC 61810 se uporablja za elektromehanske osnovne releje (neopredeljene časovne stikalne releje) za vgradnjo v nizkonapetostno opremo (tokokrogi do 1000 V izmeničnega toka ali 1500 C enosmernega toka). Določa osnovne funkcionalne in varnostne zahteve ter z varnostjo povezane vidike za uporabe na vseh področjih elektroinženiringa ali elektronike, kot so:
• splošna industrijska oprema,
• električni objekti,
• električni stroji,
• električni aparati za gospodinjsko in podobno uporabo,
• informacijska tehnologija in poslovna oprema,
• gradbena avtomatizacijska oprema,
• avtomatizacijska oprema,
• električna namestitvena oprema,
• medicinska oprema,
• nadzorna oprema,
• telekomunikacije,
• vozila,
• prevoz (npr. železnice).
Skladnost z zahtevami iz tega standarda se preveri z navedenimi tipskimi preskusi. Če uporaba releja določa dodatne zahteve, ki presegajo zahteve iz tega standarda, je treba rele oceniti v skladu s to uporabo glede na skladnost z ustreznimi standardi IEC (npr. IEC 60730-1, IEC 60335-1, IEC 60950-1).
